What if my playstyle is "enough with the arguing and let's just get the dungeon done and over with"?

For claiming your time is precious (so is everyone else's), you felt it fine to engage in a disagreement, rather than focus on the task at hand. Typing between GCDs or not, humans are terrible multitaskers and spending time in a disagreement is still a distraction and will slow the run down. You don't see who is the one who initiated the kick anyway, how do you know it was specifically over the disagreement, and not someone who had enough of listening to it and felt the need to forcibly end it?

I can only make guesses of course, but for all points you keep trying to make about why you think the kick was unjustified according to exact words, you've yet to explain the important context of what the disagreement was even about in the first place. Because yes, that DOES matter. Were you arguing over pineapples of pizza, or something specific to the run? Differences of opinion CAN AND DO have a direct affect on other people in certain contexts.
